Hyperion 32F/0C LONG sleeping bag
Top quality: the lightest down sleeping bag in its class and highly compressible, using 900 Cuin hydrophobic down.
The Thermarest Hyperion 32F/0C long sleeping bag combines all the performance you expect from a down bag when seeking warmth, compactness and low weight. The Hyperion 0 sleeping bag is an ally for hikers for whom every gram counts.
Unrivalled light weight and compactness
The Thermarest Hyperion 32F/0C long sleeping bag is the lightest sleeping bag in our 0°C to +5°C range. Weighing just 500 grams, it is the featherweight of its class.
Its goose down fill with 900 Cuin fill power also delivers outstanding quality, offering the highest fill power available on the market.
Once released from its compression sack, your Hyperion sleeping bag will feel like your duvet at home, providing excellent sleeping comfort.
The materials allow the bag to be compressed fully without damage. Rolled up, it becomes tiny and fits easily into the bottom of your backpack.
Outstanding thermal and technical performance
Not only does 900 Cuin goose down make the sleeping bag exceptionally lofty, ultralight and ultra-compact, it also provides impressive warmth for such a lightweight bag:
- The down used in the Thermarest Hyperion 32F/0C sleeping bag is Nikwax Hydrophobic Down. Treated against moisture, it stays dry, absorbing 90% less moisture than conventional down and drying 3 times faster. This technology also lets the down retain its loft 60 times longer than untreated down.
- The Hyperion 32F/0C sleeping bag has a ThermaCapture lining, trapping and retaining body heat.
- The fill is distributed differently by zone to maximise warmth where the body needs it most.
- Mesh baffles maintain loft and prevent cold spots.
The down is RDS-certified (Responsible Down Standard), sourced with respect for the environment and animal welfare. The hydrophobic treatment is guaranteed free from hazardous perfluorinated compounds (PFCs).

- Zip approximately 90 cm long with a protective flap
- Hood with drawcord adjustment
- Removable SynergyLink connectors: attach your sleeping bag to your mat for maximum comfort
